Yes!
I am planning to assign 133.* IP addresses to all guest instances.
Best,

Okay, I believe I see what youre going for now. Are you planning on
assigning 133.* addresses directly to your guest instances?

Sorry about the confusion!
I have two nodes, with two network interfaces each. One configured
with 192.* IP and one with 133.*
I can access them with SSH directly at 133.*
Both nodes can ping one another and both nodes can ping Internet
addresses e.g. google. com
No other router available for configuration.
No openstack yet.
So, my question is the following :
If I want to install openstack should I modify the external network
interface so that it doesnt have an IP address? If I do that how
can I access the server then?
I was under the impression that the document was talking about a
situation like the above when it clearly doesnt. Thats why I am
looking for new guidelines.
All the best,
George

Im not sure I understand. Are you able to ping from your nodes out
to the internet at all?

Aaron it helps a lot and thank you for that.
Unfortunately in my setup there is no router for the management
interface since it is much simpler and has two interfaces: one
that has
an external IP and connects directly to the internet and a
second one
with internal (management) network that cannot be reached from
the
outside. In such a case can you recommend a setup or point me
at a
documentation?
Thanks a lot again,
George
